§ 80.1165   Assignment and use of frequencies.

   Frequencies for general radiotelephone purposes are available to ships in
   three radio frequency bands. Use of specific frequencies must meet the
   Commission's rules concerning the scope of service and the class of station
   with which communications are intended. The three frequency bands are:

   (a) 156-158 MHz (VHF/FM Radiotelephone). Certain frequencies within this
   band are public correspondence frequencies and they must be used as working
   channels  when communicating with public coast stations. Other working
   frequencies within the band are categorized by type of communications for
   which use is authorized when communicating with a private coast station or
   between ships. Subpart H of this part lists the frequencies and types of
   communications for which they are available.

   (b) 1600-4000 kHz (SSB Radiotelephone). Specific frequencies within this
   band are authorized for single sideband (SSB) communications with public and
   private coast stations or between ships. The specific frequencies are listed
   in subpart H of this part.

   (c) 4000-23000 kHz (SSB Radiotelephone). Specific frequencies within this
   band are authorized for SSB communications with public and private coast
   stations. The specific frequencies are listed in subpart H of this part.
